Ahead of its world premiere at the Venice International Film Festival on Sept. 6, a new trailer for 100 Nights Of Hero has been released. Starring Charli xcx in her silver screen debut alongside an ensemble cast featuring Maika Monroe, Emma Corrin, Nicholas Galitzine, Felicity Jones and Richard E. Grant, the film will receive a US cinema release on Dec. 5; a U.K. release date is yet to be announced.

Directed by Julia Jackman (Pigs, Bonus Track), the historical fantasy is based on the graphic novel by Isabel Greenberg, which in turn was inspired by the Middle Eastern folktale One Thousand and One Nights. Its synopsis reads: “When a charming house guest (Galitzine) arrives at a remote castle, the delicate dynamic between a neglectful husband, his innocent bride Cherry (Monroe), and their devoted maid Hero (Corrin), is thrown into chaos.”

The teaser trailer, which you can watch below, features a montage of the cast, with a bloody Galitzine holding up a stag’s detached head, while Charli plays a medieval stringed instrument under a weeping willow.

After being briefly featured in the Prime Video series Overcompensating earlier this year – as well as serving as executive producer on the show and its soundtrack – BRIT award-winner Charli has a number of other acting projects in the works. She will appear in Erupcja, a drama she also co-wrote, which will premiere at Toronto International Film Festival on Sept. 4. On the same evening, Victim, another film starring Charli, will also be shown for the first time.

Also on the TIFF line-up is Sacrifice, an upcoming satirical action flick by Romain Gavras, which follows a celebrity charity event that is interrupted by a radical activist group. Charli joins that film in an undisclosed role. Other projects in the pipeline for the British musician include thrillers The Gallerist and I Want Your Sex, alongside The Moment, a pop star mockumentary set to come from Charli’s new production company, Studio365.

Charli headlined The Other Stage at Glastonbury Festival in June, a show which Billboard U.K. described as “a triumph of emotive pop hedonism and discomfiting intimacy”. Earlier that month, she celebrated the year anniversary of her sixth LP Brat – the record that catapulted her to global mainstream success.
